Abstract
Directed spectral measures quantify in the frequency domain directed statistical interactions between timeseries variables Most commonly the various measures are computed based on a linear multivariate autoregressive MVAR model of the data The various methods quantify in different ways the strength of interaction terms in the Fourier transform of the MVAR model While these methods are sometimes referred to as capturing “causal” or “effective” connectivity they are most properly described as reflecting “directed functional connectivity” Friston et al 2013
